AUTOMATIC FLUSI-IING APPARATUS FOR WATER-CLOSETS.

Application filed February 5, 1906.

To all whom it may concern:

Be it known that I, YVILLIAM H. OSBORN, a citizen of the United States,residing at Southern Heights, in the county of Jefferson and State ofKentucky, have invented a new.

and useful Automatic Flushing Apparatus for later-Closets, of which thefollowing is a specification.

This invention relates to apparatus for flushing water closets; and theobjects of my improvement are, to provide a water closet which willflush automatically, of which the working parts are inclosed so as to besafe from tampering and accidental derangement and hidden from view soas to avoid an unsightly and complicated appearance, simplicity ofconstruction, facility of operation, and ease and comparativeinexpensiveness of manufacture.

These objects I attain by means of the mechanism illustrated in theaccompanying drawings, in which- Figure 1 is a vertical sectional viewFig. 2, a side elevation with the near end of the tank removed; and,Fig. 3, a plan view with the tank removed.

Similar reference numerals refer to similar parts throughout the severalviews of the drawings.

The stop-valve 1, the flush-valve 7, and the seat extension or lever 5constitute the body of the invention. The tank 2 is of the ordinarylow-tank type, and the flush-valve 7 is of the conventional hollow floattype having a stem, 8, extending upward. Stem 8 passes through a guide,9. Stem 10 extends from valve 7 downward into tail-piece 31 of valveseat32 and through guide 11. Immediately under valve 7 and in its axis isthe stop-valve, 1, for the purpose of holding the water in tank 2 whenflush-valve 7 has been unseated. Stop-valve 1 has a tubular upperportion 35, provided with a collar and a union nut 33 by means of whichit is attached to part 31. The body of stop-valve 1 is somewhat onlargedto accommodate the valve mechanism. In the upper tubular portion 35 is aguide, 12, for guiding stem 10 and also for abutment of a coil spring,20. The valveseat 30 is formed on the body of the valve at the lower endof the tubular portion 35. The valve-disk 22 is provided with upwardextending guide stems, 27, adapted to bear Specification of LettersPatent.

against the inner surface of portion 35 and preserve the centralalinement of the disk. Disk 22 is also provided with two integral stems,21 and 26, extending upward and downward respectively from the disk.Over stem 21 is placed the coiled compression spring 20 so arranged asto press the disk normally downward. The disk is provided with a gasket,23, preferably made of rubber, for seating against valve-seat 30. Stem26 has a downward extension, 13, which is bored with an axial hole toaccommodate stem 26. A washer or gasket, 36, is placed over stem 26between the disk and the upper end of part 13. The lower end ofstop-valve 1 is closed by a plug, 24, which is sufficiently large sothat disk 22 may be inserted through the opening. Plug 24 is sealed witha gasket, 25. It is provided with an integral upward extending tubularportion into which stem 13 fits snugly and in which it slides on the topof which disk 22 normally rests. Plug 24 is provided on the outside witha central stuffing-box, 28, to prevent leakage about stem 13. The bodyof stopvalve 1 is provided with a union for attachment to the closetbowl. Stem 13 is provided at its lower end with a friction roller, 14,and side plates or guides 29.

The closet seat 4 is hinged to the bowl in the usual manner, ispreferably cast of metal and hollow underneath, and is provided with alug, 19, on its under surface. On the same hinge with seat 4 is pivoteda valve-operating lever, 5 by means of hinge-pin 16, which extends underthe rear end of seat 4, then backward from the hinge, encircling theflush pipe, and terminating in a flattened extension. The seat extension5 may be made integral with the seat casting 4. This extension is boredvertically at its rear end and threaded and carries a wear-plate, 15,which is vertically adjustable and adapted to work against frictionroller 14. The guides 29 extend downward on either side of the rearextension of lever 5 and wear-plate 15 and keeps these parts inoperative alinement with friction roller 14. The forward end of lever 5which extends under seat 4 is provided with a boss, 17, pierced andthreaded to receive an adjusting screw, 18. Adjusting screw 18 is usedto adjust the angle of seat 4 relative to the closet bowl and lever 5 sothat when the seat pressed down on the lower end of the lower stem ofsaid stopthe bowl, lever 5 will press disk 22 of the stop-valve firmlyagainst valve-seat 30 and yet not cause an excessive strain on lever 5and the other working parts.

The operation of the apparatus will now be understood. The tank 2 fillswith water in the ordinary way, the water being held in the tank byvalve 7. Valve 1 is normally open, stem 13 and disk 22 being depressedby spring 20, lever 5 is depressed and seat 4 is elevated at the frontend. When seat 4: is depressed at the front end by the occupant, therear end of lever 5 is elevated, stem 13 is pushed up until it carriesdisk 22 upward and presses it firmly against seat 30' Stem 21 comes incontact with stem 10 of float-valve 7 and raises it of]? its seat sothat it rises and floats in the water. The water now descends throughthe opening in the valve-seat 32 but is stopped and prevented fromflushing the closet by disk 22. VJhen seat 4 is released by the occupantrising, the front end is raised by the rear end being depressed by stem13, disk 22 drops, and the water flows from tank 2 through flush pipe 6and flushes the closet. Valve 7 reseats itself as soon as the tank isempty, and the tank is refilled in the ordinary way ready for theflushing operation to be repeated.

Having thus described my invention so that any one skilled in the artpertaining thereto may make and operate it, I claim- 1.
